CBU 105

[awdrgyjo]

I was carrying a load of CBU 105s I activated the profile as normal, and all of them were white highlighted, when the manual release cue appeared they would not drop, any ideas? thanks in advance.

Well, I'm a scrub, but I had the same problem last night and someone I was flying with was nice enough to help me troubleshoot it.

 

My problem was an incorrect alignment of EGI. If you get in a hurry on startup and don't let the alignment complete then you can't drop the weapon.

 

The indication that something was amiss was from the DSMS page, the weapons had a 'unaln' or something like that, instead of 'rdy' under their names. After being walked through an in flight re-alignment I was good to go and dropped bombs on target.

 

Hope this helps.

Spot on! the aircraft moved at the startup procedure, thanks for the reply.

Why are these things so inaccurate IRL they are wind corrected munitions yet I'm finding them miss the mark and get blown away from the tgt quite often.:doh:

Wind corrected. Not bad-targeting-corrected!

When you drop a bomb on something that subsequently blows you away the odds are reasonable that they had as much opportunity to blow you away as you approached as when you egressed- whether you missed the target or not.

 

Meaning: Probably shouldn't have dropped a bomb- and if the target WARRANTED a bomb then maybe next time drop it from a little higher... and if unable to go a little higher then maybe we need to take another look at if you should be dropping a bomb... (and repeat).

 

Just sounds like you put the wrong groceries on the wrong doorstep-

 

I get blown away plenty- believe me- but what you're saying seems a bit... off.

The bomb is wind corrected, the bomb-lets are not. If you can tell what the wind is doing always try to compensate a little bit by targeting slightly upwind. This allows your bomblets to drift with the wind over the target area as they near their dispersion point.

[SUBS17]

Ok so I'll mark with smoke first to determine wind effect thanks Grimes.:thumbup:

 

BTW after rethinking the issue I believe IRL the WMCD should compensate for all the above so IRL they should not miss at all! Because the bomb is wind corrected it means that it compensates for the munitions as well otherwise IRL this very expensive CBU would not be used much because IRL the pilot would wind up wasting them in high wind conditions. So this is definately a bug IMO that definately needs fixing.

lol ok I see a language barrier here, I was refering to the wind blowing my munitions away from the tgt.:doh:

[ENO]

Lol! Oooooh okay. Well then- right groceries, right doorstep- wrong knock!

 

I'm not quite certain as to how to figure out wind conditions on deck at the target area... And as many smoke trails you get from the rampant industrialization in the region I don't think they're a good indicator. Its an issue I have as well. In fact today I'm quite disappointed in my 97s... So just a bit annoyed at the whole dispenser right now!

[SUBS17]

Yeah the JTAC will let you know the wind strength and direction but IMO because they are wind corrected munitions they should not be blowing away from the tgt at all. Everything should be taken into account by the A-10s FCC or what ever it uses. From testing I've found 97s work good but 105s are hopeless.

[SmokeyTheLung]

into account by the A-10s FCC

That would take all the fun out of it :D

 

On a serious note, lower your HOF to the lowest feasible level. I have to do more testing on this but it seems that on level ground that's 700ft. I generally set to 900ft to be safe (with a setting of 700ft they don't always have enough time to deploy)

 

...Won't completely solve the wind issue but will improve matters by a factor of 2 (at least) and there are no adverse side affects/consequences that I'm aware of (the "spread" will remain the same with every setting, unlike the CBU 87/103 [i [i]think[/i] that might need fixing])

[SUBS17]

But thats the whole point of WMCD lol, I'll try lowering the HOF.

 

cheers
